I wonder what lamps will cost when made with these, and what
their reliability will be. They certainly look like they
could improve lots of performance details.

Way too complicated with a way too high parts count including three FETS and

IRF has unloaded their MOSFET line. This chip sure isn't going to be
the new direction of the company. There is no good reason the chip
needs so many added parts to do its job. A couple of logic lines
could tell it what tube is connected.
